SASH -FASTENER.

SPECIFICATION forming part of Letters Patent No. 372,349, dated November 1, 1887.-

\ Application filed March 24, 1887. Serial No. 232.346. (No model.) a

T0 aZZ whom it may concern:

Be it known that I, EMMA J. WHITMAN, a eltizen of the United States, residing in Oak- .land, in the county of Alameda and State of California, have invented a new and useful Window Lock and Adjuster, of which the fol lowing is a specification, reference being bad to the accompanying drawings and the letters marked thereon.

My invention relates to improvements in window locks and adj usters.

Figure 1 is a front elevation of a window with my improvement attached. sectional view showing the same cut vertically through the center of the frame and sash. Fig. 3 is an enlarged front elevation of my improved lock. Fig. 4 is a side elevation of the same. Fig. 5 is a plan view of the bolt that operates in the window-frame. Fig. 6 is a sectional plan view of my improved lock and ad jnster.

A represents the lock-bolt; B, the sleeve lockbolt set-screw; O, the thumb-piece of the set-screw; D, the bolt that catches in the win- 'dow-frame; E, the collar that forms the stop for the set-screw; F, the outer sleeve that forms the case for the lock-bolt; G, the attaching-plate for the top of the top rail of the lower sash; H, the attaching -plate for the front ot the top rail of the lower sash.

I represents the lock plate for the upper sash.

J represents the sockets for the slide-bolt D in the side of the window -frame to lock the lower sash. g

K represents the upper sash,and L the lower sash.

The following is the construction of'the same: The outer case, F, and the attachingplates G and H are cast in one .piece. The lock-bolt A is'tapped to receive the set-screw Fig. 2 is a B, and the threads are cut so as to give a quick action. I generally form the thumbpieceO small in diameter and long, as shown in the drawings, although I sometimes vary the construction of the same as may be required.

I form the lock-plate I of thin metal,and perforate it to receive the lock-bolt A, as shown in Figs. 1 and 3.

The following is the operation of the same: In lowering the upper sash, K, the bolt A is withdrawn from the lock plate I by turning the set-screw B back. Then the sash is let down until the bolt Ais opposite to the perforation designed for adjustment of the sash to the required opening. The set-screw A is then turned forward,setting the boltinto the proper perforation of the plate I. When the lower sash is to be raised .or adjusted, the slide-bolt D is adjusted in the sockets J, by which means it is held at any required point. By tightening the bolt A the two sashes K and L are set firmly against their bearings, and all rattling or shaking is avoided.

Having thus described my invention, what I claim, and (lesire'to secure by Letters Patent, is-

In windowstops, a sashfastener consisting of the case F, having attaching-plates formed integral therewith,a boltarranged in said case and internally threaded, the screw B,engaging the threads of the bolt and having a stop-collar, E, and a thumb-piece, G, the sliding bolt D passing beneath the said screw B and case, and adapted to move in a plane at right angl es with the bolt A, substantially as specified.
